Working principles of the electrophoretic miRNA preparation method. a A simple circuit model of the electrophoretic system. Each electrical component is explained in the text. b Gel image of the miRNA from human blood serum separated using the electrophoretic protocol (E) and the commercial kit (K), and the positive control (Ref). c UV–Vis spectrophotometry result of the electrophoretically collected (upper, red line) and the chemically extracted (lower, black line) miRNA. The y-axis represents the absorbance at 10 mm pathlength
